Hi there all! Greetings from a happy Grass-root GISser on an Archlinux box...
Is there already a way to analyze the new Landsat 8 images (they are already available!)? We are in particularly interested in the Normalized Standardized Vegetation Index (NDVI). We noticed a shift in wavelength range that is best depicted here: http://www.gisagmaps.com/landsat-8-about-refinements/ Doing the well-known raster map calculation with the bands 5 (NIR) and 4 (R) of L-8 doesn't give a satisfying result. Very bluntly we subtracted 0.12 from the 'ndvi' raster derived from L-8. Without doubr there must be more elegant and correct solutions. Any ideas are very welcome Cheers, ________________________________ Huub Munstege BPE 2836 Bamako, Rep. du Mali Tel: +223 20226397 Port: +223 78370695 ________________________________
